Title: Electronic distributor of electric signals controlling the operation of internal combustion engines
IPC: F02D41/36
Filed: 1969-11-13
Abstract: 1292309 Regulating IC engines; ignition systems SOC DES PROCEDES MODERNES D'INJECTION SOPROMI 13 Nov 1969 [20 Dec 1968] 55712/69 Heading F1B [Also in Division G4] A ring counter controls the distribution of signals controlling ignition or fuel injection in an internal combustion engine. The detailed description concerns the latter. The counter, Fig.2, comprises one 4-layer semi-conductor 11, which conducts as soon as the system is switched on, and three single-junction semi-conductors 12-14. Single-junction 35 is cut off while transistors 9, 10, 28, 29 conduct. Potential from point a pulses thyristor 30 to energize the solenoid controlling fuel injector 51, the duration of the injection being dependent on parameters controlling variable resistors 23-26, 34. The injection ceases when the potential across capacitor 27 energizes single -junction 35 so cutting off transistor 28. A positive pulse, such as from the ignition contact-breaker 1, stops the counter in known manner. Fig. 2 does not show a resetting circuit but a long pulse applied to a transistor (70), Fig.3 (not shown) between the anodes of 11, 12 ensures that 11 conducts to the next pulse from 1 to restart the cycle. Fig. 5 shows a similar resetting arrangement with a counter using single-junction stages only. As an alternative to the use of transistor 70 resetting is effected by amplification of a weak pulse from one of the sparking plug leads 149, the resulting pulse being applied to the first stage 11a. In arrangement of Fig. 5 responds to operation of push button 134 to produce a round of injections without rotation of the engine. Fig. 4 shows an arrangement for amplifying  and shaping ignition pulses. The injection pulses can be delayed according to the conditions of the engine, e.g. engine speed or load.

IPC: F16F1/18
Abstract: 560,542. Plate springs. SPENCER & SONS (1928), Ltd., J., and FROST, W. E. Oct. 21, 1942, No. 14770. [Class 108 (iii)] A resilient thin plate of rectilinear shape for use alone as a spring, or in a laminated spring, is slotted longitudinally so that the combined width of the portions of the plate on each side of the slot or slots uniformly increases throughout the length of the plate from its ends towards its centre, or, in the case of a cantilever spring, from one end towards the other end. As shown, the steel plate a, which may be flat or curved longitudinally, has a triangular slot b in each half, narrow transverse strips c being left at the ends and, if desired, similar strips c<1>, c<2> between the base and apex of each slot. The slots may be of different lengths. The plate or plates, when forming a laminated spring, is or are secured at the centre by bolts &c. passing through the apexes of the slots and, in the latter case, surface friction is largely eliminated by the insertion of thin distance pieces between the end strips c and central portions of the plates. When the plates form a laminated cantilever spring, bolts are also passed through holes in the ends of the plates.

Abstract: 1277159 Data storage INTERNATIONAL BUSINESS MACHINES CORP 17 Dec 1970 [30 Dec 1969] 59914/70 Addition to 1277158 Heading G4C Binary sequences are converted into interleaved NRZI form, recorded, read and then encoded by a correlative level coding process having delay by more than one digit in its encoding function. The input sequence (kth bit being ak) is converted to interleaved NRZI form in which the kth bit b k  is given by this being equivalent to dividing by 1 - D<SP>2</SP> then reducing mod 2. The interleaved NRZI form is recorded on magnetic tape, disc or drum, each 1 reversing the magnetization. On read-out, a conventional (differentiating) read head followed by a corrective filter with a cosine frequency characteristic performs the correlative encoding to produce bits c k  according to this being equivalent to multiplying by 1 - D<SP>2</SP>. The result is then divided by 1 - D<SP>2</SP> in a first decoder which feeds a second decoder which multiplies by 1 - D<SP>2</SP> and takes the result mod 2, thus reproducing the original input sequence. If any digit at the output of the first decoder is other than 0 or 1, an error signal is produced by a level detector to give a warning to the operator or cause re-reading of the recorded data.
